}Create hosted checkout link
Creates a one-hour hosted checkout URL for an existing BillingServ customer. customer_id is required and must reference a customer account (account_type 2). When the customer opens the returned URL, BillingServ signs them into a checkout-only session, shows a checkout-only page, allows saved payment methods such as Stripe cards, and redirects back to callback_url after payment.
